Hello folks! Ever wondered how to calculate your MEWS? No, not the meow of a kitty, but the Modified Early Warning Score! This nifty little equation is a lifesaver for healthcare professionals determining the urgency of a patient’s condition. But hold onto your hats, it’s trickier than your high school algebra homework!
MEWS Calculation Formula
MEWS Score = Respiratory Rate Score + Heart Rate Score + Systolic Blood Pressure Score + Temperature Score + AVPU Score

FAQs
- What is MEWS? MEWS stands for Modified Early Warning Score, a tool that healthcare professionals use to determine the urgency of a patient’s situation.
- How is MEWS calculated? MEWS is calculated using a formula that considers various patient parameters such as respiratory rate, heart rate, blood pressure, temperature, and consciousness level.
- What does a high MEWS score indicate? A high MEWS score indicates a high risk, suggesting that the patient’s situation is urgent and requires immediate attention.
- What does a low MEWS score indicate? A low MEWS score indicates a low risk, suggesting that the patient’s situation is stable.
- What is the range of MEWS scores? MEWS scores can range from 0 to 14, with higher scores indicating greater risk.
- How often should MEWS be calculated? The frequency of MEWS calculation depends on the patient’s condition, but it is typically calculated every 12 hours.
- Who can calculate MEWS? Any healthcare professional trained in patient assessment can calculate MEWS.
- Can MEWS predict patient outcomes? While MEWS can indicate patient risk, it is not a predictive tool and should be used in conjunction with other clinical assessments.
- What are the limitations of MEWS? MEWS does not consider underlying medical conditions, can be influenced by temporary factors, and requires consistent, accurate measurements.
- Are there alternatives to MEWS? Yes, there are alternative methods such as NEWS (National Early Warning Score) and qSOFA (Quick Sepsis-related Organ Failure Assessment).
